California was admitted as the 31st state of the union on September 9, 1850 and by the early 1960s it was the most populous U.S. state. The Gold Rush brought thousands of immigrants both foreign and domestic to California. This and later mass migrations, combined with the state's natural riches, assured Calfornia's success as it developed its diversified agriculture and industry, fisheries, forestry, and mining industries, aircraft plants and shipyards, tourism and recreation, the film industry, and the technological sector epitomized by Silicon Valley.
